Specification of Letters Patent.

Patented Jan. 12, 1915.

Application filed March 25, 1914. Serial No. 827,166.

To all whom it may concern:

Be it known that I, EUGENE F. TURNER, of Memphis, in the county of Shelby and State of Tennessee, have invented certain new and useful Improvements in Envelope; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled. in the art to which it appertains to make and use the same.

The object of this invention is to provide an envelop capable of being readily closed and opened when used for filing purposes; one which will present a uniform surface for printing on both sides for record purposes; and one which may be used for transporting mail matter subject to inspection but which will not allow the contents to fall therefrom.

In the accompanying drawings, Figure 1 shows the blank from which I form my envelop. Fig. 2 is a rear view showing the parts folded with the exception of the top flap. Fig. 3 is a view showing the top flap partly inserted in its retaining pocket.

Referring to the drawings, the blank from which the envelop is formed comprises a rectangular body portion 1; lateral flaps 2 and 3; a lower flap 4, and a top flap 5. The lateral flaps 2 and 3 are of the same depth as body portion 1 and in length about twothirds the width of the latter, and the flap 3 is designed to be superimposed on and attached to flap 2 by a gummed surface 6 on the inner face of flap 3.

The lower flap 4 is gummed on its inner face, adjacent to its side edges, as indicated at 7, such gummed surfaces extending from the inner to the outer edges of such flap. In addition to the gummed surfaces 7 by which the lower flap 4 is secured to the outer faces of the lateral flaps 2 and 3, such lower flap is also gummed at 8 from a point about midway its upper and lower edges to about the parallel line 9, and also diagonally outward as indicated by the diagonal lines 10. This lower flap 4 is of the same width as the body portion but of decidedly less depth, that is to say, when the lower flap is folded over the end flaps its upper edge is short of the upper edge of the body portion for quite a decided distance. A pocket is formed by the lower flap, that is to say, by the inverted truncated cone shaped space presented between the upper edge of the lower flap, the

line 9 of the gummed portion 8, and the diagonal lines 10 of such gummed portion.

The top flap 5 is in the form of a segment of an octagon, that is to say, it has opposite diagonal edges 12 which are connected by a straight line 13 presenting a blunt end which may readily be inserted into the pocket formed by the upper edge of the lower flap. The line of connection 14: between the upper flap and the body portion is scored.

In forming the envelop the gummed surface of the lateral flap 3 is folded down over the outer surface of the lateral flap 2; the lower flap 4 is folded up over the lateral flaps and is secured thereto along its side edges by the gummed surfaces 7 and also by the gummed portion 8, leaving a pocket between the outer surfaces of the lateral flaps and the inner surface of the lower flap and into which pocket the ungummed top flap may readily be inserted and securely held without gumming. \Vhen the envelop contains books or pamphlets, the top flap 5, being scored along the line 1 1, curves forward and downward over the lateral flaps so that the force of the impact of the contents upward is shunted backward toward the body portion and is borne mainly by the body of the envelop rather than by the inclosing flap, which latter is sufficiently firmly held to withstand rough handling in the mail without danger of working out of its pocket.

Although my envelop may be of advantage for mailing, yet it is especially designed for filing, the smooth and unbroken surfaces of the body portion and bottom flap being capable of being printed upon for record purposes, the contents of the envelop being capable of identification and classification on the outside thereof.

I claim as my invention:

1. The envelop herein described, composed of a blank having a rectangular body portion, lateral flaps corresponding in length to each otherbut of less length than the body portion, one flap being gummed on that portion of its inner surface which overlies the other flap for securing the two flaps together, a lower flap of the same width as the body portion but of less depth than the latter, said lower flap being gummed along its opposite side edges and also along its inner face from about the center thereof and about half way to its upper edge and diagonally outward to the gurnmed surface along the side edges, said gummed portions of the lower flap being designed to be secured to the outer surfaces of the lateral flaps, and the unguinined surface at the top center of said lower flap forming a pocket, and a closing flap extending from the upper edge of the body portion and having oppositely inclined edges, forming a blunt end which is designed to conform to and fit in the pocket formed by the lower flap.

2. The envelop herein described composed of a blank having a rectangular body portion, lateral flaps designed to be secured together when folded over the body portion, a lower flap of the same width as the body ing witnesses.
